' CONVEYER-BELT.

Specification of Letters Patent.

Patented May 11, 1920.

To all whom it may concern Be it known that 1, JOHN G. FREY, a citizen of the United States, and a resident of the city of Middletown, in the county of Orange and State of New York, have invented certain new and useful Improvements in Conveyor-Belts; and I do ereby declare that the following is a full, clear, and exact description of the same, reference being had to the accompanying drawings, and to the numerals 0 reference marked thereon, which form: a part of this specification.

This invention relates to an improved form of conveyer'belt which is constructed by assembling interfitting metallic members with the belt at predetermined distances therealong to afford partition walls, thus dividing the conveyer belt into a series of pockets. A. belt of this type is shown and described in the pending application for patent of Charles J. Lietz, for Wrapping machine, filed March 17th, 1917, Serial No. 155,420. This belt is particularly desirable for use in feeding mechanisms wherein a timed feeding of articles is required for the reason that the members which form the partitions for the pockets in the belt also serve as an engaging means for wheels around which the belt is trained, and by which the belt is driven.

It is an object therefore of this invention to construct a conveyer belt having a plurality of pockets therein, and with means projecting from the belt for engagement with a driving wheel around which the belt is trained so that a positive and predetermined character of drive may be imparted to the belt.

It is also an object of this invention to construct a conveyer belt having 'a plurality of carrying pockets therein and with means for engagement with a driving mechanism whereby a predetermined drive may be imparted to said belt without slippage for a timed movement of the pockets which carry the articles on the belt.

It is furthermore an important object of this invention to construct a conveyer belt having a plurality of pockets formed on one side of the belt for reception of articles, and with the partition walls of said pockets extended on the other side of the belt to afford means for a driving mechanism, whereby the belt is moved.

Other and further important objects of the invention will be evident from the disclosure in the drawings and specification.

The invention (in a preferred form) is illustrated in the drawings and hereinafter more fully described.

On the drawings:

Figure 1 is a fragmentary top plan view of a feeding and receiving mechanism showing adaptation of a belt embodying the principles of my invention thereto.

Fig; 2 is a side elevation thereof.

Fig. 3 is an end view of one of the belt wheels shown in Figs. 1 and 2.

Fig. 4 is a fragmentary edge view of the conveyer belt.

Fig. 5 is a similar view showing the same in section.

Fig. 6 is a sectional detail taken on line 6-6 of Fig. 4.

Fig. 7 is a detail view illustrating the assembly of the partition members of one of the belt pockets. 7

Fig. 8 is an enlarged sectional detail illustrating the manner in which the free ends of the belt are connected.

Fig. 9 is a section on line 9--9 of Fig. 8.

As shown on the drawings:

The reference numeral 1, indicates a feeding tray with convergent walls -or ribs 2, formed on the upper surface thereof, and secured on the under side of said tray are bearing members 3. At a point removed .from .the feeding tray 1, is a receiving tray 4, and secured thereto are upwardly extending bearing brackets 5. Secured in attached relation between the feeding tray 2, and receiving tray 4, is a horizontal channel guideway 6. Journaled in the bearings 3, of the feeding tray 1, is a shaft 7, on which is secured .a notched pulley or sprocket wheel 8, the notches of which are denoted by the reference numeral 9. Similarly, journaled in the bearing brackets 5, is a shaft 10, on which is secured a notched pulley or sprocket wheel 11, the notches in which are also denoted by the reference nu meral 9. Trained around said respective sprocket wheels 8 and 11, is a conveyer belt embodying the principles of my invention.

This belt consists of a continuous strip of fabric, leather, rubber, composition, or any suitable material for the purpose, denoted by the referencenumeral 12, and at p d t mined Pa n eel ng; -sh pe plates 13, are fitted perpendicularly thereto with the belt fabric folded therearound in U-form, as denoted by the reference numeral 14. End projections 15, are formed upon each of said plates 13, at the upper edge thereof, and a downwardly extending tongue or tooth 16, is formed centrally at the lower edge of each thereof.

Engaged over each U-formed portion 14, of the belt, is an oblong ferrule 1'7, which isthrust upwardly closely beneath the end projections 15, of the plate 13, thus confining the U-shaped portion 14:, of the belt, around said plate 13, with the tongue portion 16, depending beneath the belt. During the actual assembly of the pocket forming members of the belt, the ferrule 17, is first engaged over a loop 14, of the belt, as shown in Fig. 7, and the plates 13, are then introduced between the folds of the U-portion 141. l The ferrule 17, is then moved upwardly to clamp the belt material securely around the plate 13.

.As shown in Figs. 5, 8 and 9, a slightly different form of insert plate 13, is used to fasten the free ends of the belt together to form a continuous belt. That is, the T- shaped plate 13, used for this purpose,'is provided with grooves 18, on each surface near the upper end of the plate, and when assembled with the belt, the edgesof the ferrule 17, are pinched inwardly to thrust the belt material into the grooves and engage the belt ends tightly to the insert plate.

The articles upon the tray 1, are fed through the converging walls 2, onto the belt 12, one article falling into each pocket of the belt, and the articles are then conveyed thereby for discharge to the receiving tray 4. This mechanism, however, is only shown for the purpose of illustrating a means of adaptation of the conveyer belt, as'it has a wide range of use.

I am aware that various details of construction may be varied through a wide range without departing from the principles of this invention, and I therefore do not purpose limiting the patent granted otherwise than necessitated by the prior art.

I I claim as my invention:

1. A conveyer belt having a plurality of pockets formed therein, a plate engaged with said belt, a ferrule wedgingly engaged over the loop of belt material to secure the same tightly to said plate to form a wall of a pocket, and a tongue extension formed integrally on said plate said tongue extension projecting away from the plane of the belt.

2. A conveyer belt having a plurality of pockets therein, and an integral plate disposedbetween each of said pockets and exgznding above and below the plane of the It. V

3. A conveyer belt having a plurality of pockets formed therein, said pockets formed by flat-sided walls perpendicular to the plane of the belt each comprising a plate having the I belt material. folded around one. edge thereof, a ferrule engaged over said folded portion of the material to hold the same secured to said plate, and each of said plates having a downwardly extending tongue extending beneath the under surface of the belt.

4. A flexible conveyer comprising a belt, a plurality of members secured at intervals apart to said belt, grooves in opposite sides of the members, members adapted to fit over the aforesaid members and beltadapted to crimp the belt into'said grooves, and members projecting below the belt adapted to be engaged by a sprocket wheel to drive the belt at a uniform speed.

5. A conveyer belt of flexible material,

rigid partition members secured at points along said belt extending above and below said belt, projections on the ends of said partitions and members on the belt and partition engaged, by the projections !to hold the belt and partition members associated.

6. A conveyer belt comprising a continuous strip of material, partiti'oned'members engaged therewith, and around which the material is folded, end extensions on said 7 partitions, and means confining the folded material to said partition members engaging under the end extension- 7. A device for joining'the ends of a belt together comprising a grooved insert plate against which the belt ends are laid, and a ferrule engaged over said associated ends and plate to hold the ends tightly engaged in the grooves of said plate.

8. A device for forming a partition in a belt comprising an insert plate extending above and below the plane of the beltand against which portions of the belt are laid on each side thereof, and a ferrule engaged over the belt portions on said plate to clamp 1' wheels, and a ferrule wedgingly engaged with each of said bights and plates to hold .them firmly but releasably in, secure rela tion.

In testimony whereof I have hereunto; subscribed my name in the presence of two subscribing witnesses.
